I originally asked this as a follow up on this thread, 8va or clef change? but it was suggested by "Elements in Space" (thanks, Elements!) that I should ask this as a new question, and link to the original post if I think it relevant. It is, so I have - but I get why he suggests askig a new question. It's an old post for starters - I hadn't paid enough attention to the date until his comment. So heres my post:

Some background/why I'm asking I wrote an opus several years ago, and completed 3 of the movements before getting side tracked and never finishing the third. Having just migrated a bunch of my projects over to a new PC, I came across my MuseScore folder (and got excited about MuseScore 4 and the realistic sounds, not to mention the great visual changes they brought in for v3.6 that groups your instruments for you without any input from the composer. No more manual bracketing! Wayhay. Anyway, I digress...)

So, in importing my scores into MuseScore 4, I have decided to complete my little string quartet project. I have a question, promise! So, during my first movement, I've got an 8va clef for violin first chair, and it pretty much stays in that area for the whole piece. Chair two is using a normal clef. As the movement draws to it's end, 26 bars (plus two repeating sections, so without counting its 40+ bars) I've got a 8va clef on chair two, which I mark on the stave, and there it remains until the close of the movement, and around the same area, chair one has a 15va clef, again marked on the stave and in this octave it remains until the movement ends.

My reason for using the clefs instead of ledger lines is that it looks (to me) much more readable and contained within the page boundaries rather than having a whole heap of ledger lines. I'm not a violinist, I'm a guitar and bass player. At the time of composing, I did ask a cellist what they thought and whether I'm following the correct convention.

Questions My question I guess, and how I found this post, was that during my importing this into MuseScore 4 from v2, I re-read through my opus, and hesitated. Is it enough just to have the 8va/15va clef being on the stave at the point of change, as well as at the start of the subsequent new lines post-change, or should I have some system/stave text to draw the players attention to this?

On googling 8va clef convention, I found this post and having read the questions I think this is a great place to ask! Thanks in advance for your insight(s).

I've put a couple of images of my score on imgbb if you find that helpful - I like to visualise things before I answer, so maybe you'll find it helpful also.
